This relates to an improved container tamper evident bead and neck finish arrangement which provides improved tamper evident band breakage upon removal of an associated closure. Most specifically, beneath the customary retaining bead, a container neck finish is of corrugated or scalloped configuration and is of a size whereby the tamper evident band or a retaining bead thereof is stretched across the space defined by a groove between two adjacent ribs so as to provide for a degree of interlock between the stretched tamper band and the container neck finish such that the tamper evident band is restrained against rotation with the remainder of the closure when the closure is rotated to effect removal thereof. This provides for a much quicker and more reliable breaking of the webs joining the tamper evident band to the closure skirt.

A container neck finish including an end sealing surface, closure retaining means, and a tamper band retaining bead spaced axially below said closure retaining means from said end sealing surface, said neck finish having a portion axially below said retaining bead being of a corrugated outline forming means for circumferential tensioned interlocking with a circular inner surface of a closure tamper band to resist rotation of a closure tamper band when a closure is rotated for removal.
